either the guest physical or the host virtual is fine with me. but better to be guest physical. i think guest physical can be obtained by subtracting host virtual with a fixed offset for ram. but the thing i do not know how to do is how to pass the guest physical back, can i store the guest physical in the TCGv from the guest virtual.
